The sodium alanate material used to store the hydrogen resides within the tubes. Researchers at Sandia National Laboratories have successfully designed and demonstrated key features of a hydrogen storage system that utilizes a complex metal hydride material—sodium alanate. Sandia researchers point out that the system was not meant to fit on board a vehicle, and that sodium alanate will not be the material of choice for onboard storage of hydrogen.

A second loop, located at Sandia in Albuquerque, is used to research the unusual issues of compression, bearings, seals, and friction that exist near the critical point, where the carbon dioxide has the density of liquid but otherwise has many of the properties of a gas.

Simple diagram of the heated un-recuperated supercritical CO 2 Brayton loop.
